RM ceramic grinding media

RMCeramic Polishing Media

  • 1. Light cutting and grinding performance, long service life
  • 2. Low Ra surface roughness produced
  • 3. Suitable for small size burr removal and light surface cutting

RM ceramic grinding media is produced by mixing porcelain, kaolin,clay, river clay or other vitreous abrasives. The wet material is formed into desired shape (usually by extrusion and cutting) and then fired to vitrify. Fusion bonding is used to make some media. Such media are available in a wide range of shapes and sizes. Also, when the engineer selects the proper grade of abrasive, the correct proportion of abrasive to binder, and the most suitable binder, this media will adapt to a great variety of application, and workpieces.

The binder acts as a burnishing surface, and this works against rapid cutting.

Deburring is an age-old technique when it comes to metal finishing. The shiny finish and the polished edges are achieved through deburring the product. Although there are different types of deburring media available, ceramic is the ideal choice for metal products.

In this article, we’ll know in-depth on what ceramic media is and how it works. Let’s get started without any delay because it’s going to be a smooth one, like your metal surfaces.

What is Deburring Media?

The term ‘media’ has different meanings in different circumstances. For metal works, media is something that helps achieve the polished look on the product. The media has to be something strong to cut through the hard metal but not to the point where it starts damaging it.

The media performs an abrasive action on the product to shape and cut the metal without damaging it. It usually contains a bonding agent and formulation to perfect the deburring. As the material is being cut down, the media wears out as well. But the wear and tear are consistent across the surface so the shape of the media remains the same.

The ceramic deburring media is, obviously, made of ceramic. It’s the perfect choice of media to deburr metal products. It breaks the edges, cleans and gives a consistent finish to the surface of the product.

There are different factors that influence how a metal product will turn out. The size of the media, the shape of the media, the size of the abrasive particles and the mineral composition are the primary ones.

How to Choose the Right Media

Although we are discussing the ceramic deburring media, it doesn’t mean it’s applicable in all cases. Different tasks require different types of media. Let’s take a closer look.

1.     The Goal

The first and the most important metric of choosing any deburring media is what you are trying to achieve. Deburring, polishing or cleaning requires different media. For example, ceramic deburring media is best for heavy deburring and cutting. Ceramic deburring media deburrs hard burrs across the surface.

Ceramic deburring media is a good choice when you need a small media. Ceramic also works great with plastic as there are different abrasive types available.

Then there is porcelain media. It’s derived from ceramic deburring media and available in cylindrical and spherical shapes. Porcelain works great when your goal is to polish and shine the metal product. The porcelain deburring media comes after the actual deburring. If you’re polishing hard metal like stainless steel, using the cylindrical shape is ideal. Spherical ones work great with softer metals like aluminum.

2.     The Size

The size of your product is a very important factor when it comes to ceramic deburring media. The wrong size of media can destroy the whole product. The most important thing to remember is that big is not always better.

You need a larger size ceramic deburring media when your product is actually large. Larger surfaces tend to have more burrs and uneven surfaces than small ones. A large ceramic deburring media will rapidly cut through the metal giving you a consistent and cost-effective finish.

It’s important to use small media for small products. Using a large media on a small surface will fatally damage it. On the other hand, using small media on a large surface will quickly wear through the media without giving you any significant results.

3.     The Features of Your Product

Finally, the features on your specific product determine what kind of and what size of ceramic deburring media you might need. In general, it’s good to undersize the media by 1/3 or oversize it depending on the lodging point.

Let’s take an example. If your media dimension is 1”, it’s more likely to be lodged in through a 1” hole. By adjusting the size, you can prevent it from lodging and achieve the intricate details you are hoping for.

4.     The Shape of the Media

Angle stars, pyramids, and cone-shaped media are perfect form cutting the metal without lodging into the part. Cylindrical angle cuts are best for passing through holes.

RSS medium grade ceramic deburring media with an angle cut is the most commonly used. It’s perfect to use with tumbling machines, rumbling machines and vibratory finishing machines.

If your primary goal is to break the edges, a 10×15 medium-sized media is a perfect choice for you. The best part about ceramic deburring media is that you can use it to perform a variety of tasks on a variety of products, mostly made of hard ferrous metals and plastic in some cases.

Don’t get intimidated by the term ‘ferrous’. It simply means metals that contain a high amount of iron in them.

Choosing the right ceramic deburring media size and shape might take you a few tries. It’s completely normal. Once, you get the perfect size and shape, there is nothing that can stop you from getting the desired finish you want.

Preserving the Ceramic Deburring Media

The worst thing you can do to a deburring media, especially ceramic deburring media is to use it on a dry surface. It’s obvious that surface finishing machines rigorously cut and deburrs the metal while creating a lot of heat.

When the media gets overheated, it loses its effectiveness while terminally damaging it. Always use the wet process to deburr metal surfaces. Simply use water while deburring in a surface finishing machine. It will keep the ceramic deburring media nice and cool while giving the metal product an extra shine. It will also prevent metal dust from going all over the place.

Take Away

Ceramic deburring media holds a special place in the machining industry and there are good reasons for that. The versatile approach and effectiveness of the media have made it one of the most commonly used deburring media all over the world.
